I don't quite understand what you're trying to do, but I can offer some advice. > index = self.__abet[a] The previous line is pointless currently. I don't understand what you expect it to do, considering you completely overwrite 'index' in the very next line. > index = [ ] > > index = index.append(rhythm.rhythmTwist(b, c)) Important Note: .append() modifies the list *in-place*. It does *not* return the modified list, it returns None. You probably want to eliminate the 'index =' part of the previous line. > > This doesn't do what I expect (probably because I don't have a clue what I'm > doing!): initalizing, then filling new arrays, each new one called A[ ], > then B[ ], etc. You probably want a dictionary of names to lists then, the names being items of __abet and the lists being the corresponding 'index'. It likely goes without saying, but you ought to read the fine tutorial as well.
